aware invention relatesto. improvements; in

operating lever means for rotary bars of (100 fasteners.

One object of the invention is to provide operating lever means ofsimple and rugged design for door fasteners of the rotary bar typeemploying a tubular operating bar having an operating lever handle fixedthereto for rotating the same, wherein the lever is secured to the barby a welded connection, designed and constructed in such a manner as torelieve the welded joint of the connection of torsional strain to whichthe parts are subjected in efiecting rotation of the operating bar inforcing the doors open or closed.

Other objects of the invention will more clearly appear from thedescription and claims hereinafter following.

In the accompanying drawing forming a part of this specification, Figure1 is an end elevational view of the body of an automobile truck providedwith hinged doors and a rotary type of door fastener, illustrating myimprovements in connection therewith. Figure 2 is an enlarged brokenview of the mid portion of the right hand door, as illustrated in Figure1, showing a portion of the rotary operating bar of the door fastenerand the operating handle lever for the bar. Figure 3 is a horizontalsectional view, on an enlarged scale, corresponding substantially to theline 3--3 of Figure 1. Figure 4 is a vertical sectional view,corresponding substantially to the line 4-4 of Figure 3.

In said drawing, indicates the end wall of the body of an automobiletruck, provided with the usual door opening I I, closed by hinged doorsl2 and H3. The door l2, the inner edge of which overlaps the inner edgeof the door I 3 in the closed position of the doors, has the doorfastener l4 mounted thereon. The door fastener I4, which is indicated indotted lines, is of the rotary bar type, which is Well-known in thisart, and comprises the usual rotary bar provided with keeper engagingmeans at opposite ends engaging With fixed keepers mounted on the bodyof the automobile truck above and below the door [2.

In carrying out my invention, I provide broad- 1y a hollow tubular bar Awhich forms the rotary bar member of the door fastener, and an operatinghandle lever B fixed to the bar A for effecting rotation thereof inforcing the door l2 open or closed.

The tubular bar A is of circular cross section and has the operatinghandle lever B secured thereto at a point between the upper and lower 3Claims. (01., ear-52.02),

ends oil-the. bar, the handle; lever B-,-bein g.1ocated sQva/SftGlswing, into arpocketrlh provided at the outer side of the door l2 whenthe door is forced to closed position by the door fastener.

The handle lever B is in the form of an elongated arm having a hand gripportion I6 at its outer end. The arm of the lever B, inwardly of thehand grip portion I6, is of channel-shaped, transverse section, having alengthwise extending, vertical web 5?, provided with laterally outwardlyprojecting, top and bottom flanges l8 and H), which extend lengthwise.At the inner end of the channel-shaped arm portion, the lever B isprovided with an arc-shaped wall portion 20, which is a continuation ofthe web I1 and fits the curved outer surface of the tubular bar A andextends partly around said bar. The wall 20 terminates in a hook portion2|, which is engaged within and extends through an opening 22 providedin the wall of the tubular bar A. The end of the hook portion 2| is bentoutwardly to provide a lip 23, which engages the inner side of the wallof the tubular bar A, beyond the opening 22. The inner end portion ofthe lever B is Welded to the tubular bar A at two zones, as indicated at24 and 25, the welded joint 24 being made by filling in welding metalbetween the outer side of the bar and the inner side of the handle leverat the point where the arc-shaped wall portion 20 merges with the web llof the handle lever, and the welded joint 25 being made by filling inwelding metal in the opening 22 of the tubular bar A between the wall ofthe opening 22 and the outer side of that portion of the hook of thelever B which extends through said opening. The lever B is thus firmlysecured to the bar A.

As will be evident, the hooked connection of the lever B of the bar Aserves to greatly reduce the strain on the welded joint between thelever and the bar, due to the shouldered engagement between the leverand the bar at the hooked connection thereof when the lever is swung torotate the bar in either clockwise or contraclockwise direction, asviewed in Figure 3, the lip 23 of the hook of the lever acting as afulcrum element to force the arc-shaped wall 29 into gripping contactwith the outer side of the bar when the lever is swung inwardly towardthe door to rotate the bar in contra-clockwise direction, forcing thedoor closed.

I claim:

1. In a device of the character described, the combination with arotatable hollow tubular bar; of an operating handle lever for rotatingsaid bar, said lever having the inner end portion thereof partlysurrounding said bar; a hooked extension at the extremity of saidsurrounding inner end portion engaged through an opening in said bar;and a welded connectioln between said lever and said bar at said innerend portion of the lever.

2. In a device of the character described, the combination with arotatable hollow tubular bar; of an operating lever having an arc-shapedwall at its inner end extending from said lever and partly surroundingsaid bar; a hook at the outer end of said wall engaged through anopening in the wall of said bar; a lip at the extremity of said hookengaged with the inner side of the wall of said tubular bar at a pointbeyond the opening through which the hook extends; and a weldedconnection between said lever and said bar at the inner end portion ofthe lever.

3. In a device of the character described, the combination with arotatable hollow tubular bar; of an operating lever having an arc-shapedwall at its inner end extending from said lever and partly surroundingsaid bar; a hook at the outer end of said wall engaged through anopening in the wall of said bar; a lip at the extremity of said hookengaged with the inner side of the wall of said tubular bar at a pointbeyond the opening through which the hook extends; a welded con-REFERENCES CITED The following references are of record in the file ofthis patent:
